BIS Certification for Synthetic Enamel Paint IS 2932 (Part 1)

BIS Certification for Air Drying Enamel Paint for Architectural & Industrial Application is one of the leading standards regulating the production of coating materials meant to protect buildings, infrastructure, industrial structures and metal surfaces. Air drying enamel paints are popular because of their smoothness, colour fastness and gloss.

With the increasing demand for quality paints across India, obtaining compliance from regulators has become vital for paint producers in this country. The IS 2932:2025 standard prescribes the main requirements concerning composition, physical and operational characteristics of paints, their testing and quality control, etc. For BIS certification, paint producers must prove their compliance by passing a series of tests and quality audits, after which the manufacturers get permission to put the ISI Mark on their product packages.

What does IS 2932:2025 Cover

This is the Indian Standard for Air Drying Enamel Paint used for architectural, decorative, and industrial surface protection applications. The standard specifies durability and testing requirements for synthetic enamel paints to ensure a long-lasting finish, weather resistance, and reliable surface protection. As per the Bureau of Indian Standards (BIS), air drying enamel paint is:

Tested for gloss retention
Checked for colour and finish consistency
Assessed for drying time
Evaluated for durability

BIS Registration Process for IS 2932:2025

The BIS Authorisation process ensures that the Air Drying Enamel Paint for Industrial and Architectural Use meets the required performance standards. This process is set by the Bureau of Indian Standards (BIS) and includes the following steps:

Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for chemical composition, silica content, moisture content, fineness, compressive strength, and other physical performance parameters.
Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
Factory Inspection: The Bureau of Indian Standards officials inspect the manufacturing units to verify the production process, safety measures, and quality control system.
Grant of BIS License: Upon successful verification of all requirements, BIS grants the certification license under Scheme-I.
Use of ISI Mark: Once approved, the manufacturer can use the ISI mark on the product with a CM/L number, confirming that the product meets BIS standards.
